FEED DEVICE FOR LOCOMOTIVES.

SPECIFICATION forming part of Letters Patent No. 530,998, dated December18, 1894.

Application filed August 18, 1894.

To all whom it may concern:

Be it known that I, LAZER LAZERUS, a citizen of the United States,residing at Indianapolis, in the county of Marion and State of Indiana,have invented certain new and useful Improvements in a Combined Blastand Fuel-Feed Device'for Locomotives, of which the following'is aspecification.

The object of my said invention is to provide a means, whereby fuel maybe either partly or wholly supplied to a locomotive, and

the combustion of such fuel may be accelerated. f

A locomotive and tender provided with my said invention will be'firstfully described and the novel features thereof then particularlyReferring to the accompanying drawings, which are made a part hereof,and on which similar letters of reference indicate similar parts, Figure1 is a view of a tender and a said invention, the side of the locomotivebe ing broken away to show the apparatus more on the dotted line 2 2;Fig. 8, an end elevation of the tender, as seen from the dotted line 33; Fig. 4., a detail View of the upper end of the escape pipe and safetyvalve, and Fig. 5 a detail ofthe union'between the hydrocarbon and airpipes.

In said drawings the portions marked A represent the locomotive boilers,including the fire-box or combustion chamber; B, the tender; 0, thesteam cylinders of the air pumps; D, the air cylinders of said airpumps; E, a steam-pipe leading from the locomotive boiler to the steamcylinder 0; F, a pipe leading from the compressed air reservoir to thelocomotive fire-box; G,a gage attachedthereto; H, an escape pipe, and Ia hydrocarbon receptacle. V I

The locomotive'A is or may be of a usual or any desired construction,and has the usual which a locomotive-is usually supplied.

The tender B isof'a different construction the drawings, and is providedwith an air chamber B which is adapted to receive and hold compressedair, and this chamber is usu- Serial No. 520,701- (No model.)

' ally and preferably of considerable capacity and ispreferably locatedat the bottom of the tender below the fuel space in front of thefire-box of the locomotive.

l The steam cylinders C may be of a usual construction for pumpingpurposes, and are provided with steam from the locomotive boiler throughthe pipes E. The piston O is preferably bifurcated, and each branch, 0',leads to and operates in, one of the two attached air pumping cylindersD, as shown. There-are preferably two of these steam cylinders, 0ne oneach side of the tender, as shown.

The air-pumping cylinders D are preferably four in number, two to eachsteam cylinder, and are operated in a usual and well known manner fromsaid steam cylinders.

Pipes D lead therefrom and discharge into the air reservoir B.

The pipes E are ordinary steam pipes, and preferably leadfrom the steamdome on the locomotive boiler to the steam cylinders 0. As they passbetween two moving parts they are provided with the usual flexiblecouplings common to" such constructions, and are also provided withsuitable valves, as e, whereby the stream may be turned on and off atpleasure.

The pipe F leads from the air reservoir B" directly to the fire-box A,where it has a nozzle F pointing into said fire-box. A valve F isprovided to turn on or off and regulate the blast of air. A branch pipeF leads up to the gage G, and thislatter serves to indicate the voir,and when the pressure exceeds what has been predetermined, the springswill yield and a portion of the air escape.

The hydrocarbon receptacle I is a tank .or reservoir of anyconvenientshape and size secured in or upon the tender, and a pipe 1'leads therefrom down to and connects with the pipe F in such a mannerthat hydrocarbon from said receptacle may mingle with theinto thefire-box and acts both as a blast and as an addition to the fuel,assisting materially in both particulars in making a hot fire, and thusgenerating the steam. The air reservoir or tank B is always kept chargedwith a suificient quantity of air so that this apparatus may be put inuse at once when desired, without waiting for the generation of steamafter a fire is first kindled, although, as is well known, a smallamount of steam is generally kept up in a locomotive, and, therefore,the air can ordinarily be pumped whenever desired.

My said invention is not only applicable where, as has so far beendescribed, ordinary fuel is used, but it is of especial value where ahydrocarbon fuel is exclusively used, in which case a hydrocarbon tankor reservoir would occupy a large portion of the space in the tender, orsubstantially the same space as is usually provided for the fuel; andthe small hydrocarbon tank could then be charged from time to time fromthe larger tank, or, by appropriate attachments, the fuel could beconducted directly from such larger tank to the air pipe.

Having thus fully described my said invention, what I claim as new, anddesire to secure by Letters Patent, is

l. The combination, with a locomotive and its tender, of an air pumpingapparatus secured to said tender, an air reservoir or tank within saidtender with which said pumping apparatus connects, a steam-pipe leadingfrom the locomotive to said pumping apparatus, to furnish steam foroperating same, and an air pipe leading from said air reservoir or tankto the fire-box ofthe locomotive, the section between the tender andlocomotive being provided with a suitable coupling said several partsbeing arranged and operating substantially as set forth.

2. The combination of a locomotive provided with the usual fire-box,atender provided with an air reservoir or tank, an air pumping apparatusmounted upon said tender, a steam pipe leading from the locomotivetosaid pumping apparatus whereby it is operated, connections between theair cylinders and said. reservoir or tank, a pipe leading from saidreservoir to the fire-box of said 10- comotive, and an escape pipeprovided with a safety valveconnected to said reservoir or tank.

3. The combination of the locomotive A having the fire-box A, the tenderB having air reservoir or tank B, the air-pumping apparatus consistingof steam cylinder 0 and air-pumping cylinders D D, a-bifurcated pistonoperating from said steam cylinder to said air-pumping cylinders, pipesD D from said air-pumping cylinders to said air reservoir or tank 13, apipe F leading from said air reservoir to said fire-box where it isprovided with anozzle F, a branch pipe F terminating in a gage G, avalve F ,\a steam pipeE leading from the locomotive to the steamcylinder 0 and provided with a valve e, and an escape pipe H having acap l-I' secured thereto by bolts h and springs h, the whole beingcombined, arranged andoperating, substantially as shown and describedand for the purposes set forth.

4. The combination of a locomotive, its tender, an air reservoir in saidtender, an air pumping apparatus mounted on said tender and connectedwith said reservoir, a pipe leading from the locomotive tosaid pumpingapparatus to supply steam for operating the same,

a pipe leading from said reservoir to the fire box of the locomotivewith a suitable coupling in the section between the tender andlocomotive, a hydro-carbon reservoir and a pipe leading from saidhydro-carbon reservoir to said air. pipe with which it communicates by asuitable connection and suitable valves for controlling the How ofhydro-carbon, air and steam through the difierent parts of saidapparatus, substantially as set forth.

In witness whereof I have hereunto set my hand and seal, atIndianapolis, Indiana, this 10th day of August, A. D. 1894.
